El hábito y la forma de crecimiento en la tribu Cacteae (Cactaceae, Cactoideae)

Abstract

Los términos ‘forma de crecimiento’ y ‘hábito’ con frecuencia se usan como sinónimos; sin embargo, su asignación a las diferentes especies resulta problemática en algunos grupos taxonómicos debido a la diversidad morfológica; éste es el caso en Cactaceae, particularmente en la tribu Cacteae de la subfamilia Cactoideae. Se estudió la morfología del tallo de 102 especies (26 géneros) de Cacteae con el objetivo de identificar el hábito y reconocer cuántas formas de crecimiento se presentan en la tribu, así como para hacer una distinción clara entre los términos ‘hábito’ y ‘forma de crecimiento’ para Cactaceae y discutir sus diferencias respecto a los conceptos de forma de vida y arquitectura vegetal. Con base en las observaciones y mediciones para 102 especies de Cacteae se reconocieron cuatro formas de crecimiento (cilíndrica, columnar, globosa y globosa-deprimida). Por su tamaño y longevidad no es posible utilizar los términos ‘árbol’ o ‘hierba’ para las especies de Cacteae. El 12% de las especies estudiadas de esta tribu tienen ramificación basítona (arbustos) como Acharagma roseana, Ferocactus pilosus y Thelocactus bicolor . Sugerimos utilizar únicamente el término ‘forma crecimiento’ para referirse a los tallos de la tribu Cacteae con la finalidad de evitar confusiones.
